How to convert Vector with string to String array in java?
simplest method would be String [] myArray = myVector.toArray(new String[0]);
try this example
Vector token
String[] criteria = new String[tokenVector.size()];
tokenVector.toArray(criteria);
Vector<String> vector = new Vector<String>();
String[] strings = vector.toArray(new String[vector.size()]);
Note that it is more efficient to pass a correctly-sized array new String[vector.size()]
into the method, because in this case the method will use that array. Passing in new String[0]
results in that array being discarded.
Here's the javadoc excerpt that describes this
Parameters:
a - the array into which the elements of this list are to be stored, if it is big enough; otherwise, a new array of the same runtime type is allocated for this purpose.
Try this:
vector.toArray(new String[0]);
Edit: I just tried it out, new String[vector.size()]
is slower then new String[0]
. So ignore what i said before about vector.size(). String[0]
is also shorter to write anyway.
Try Vector.toArray(new String[0]).
P.S. Is there a reason why you're using Vector
in preference to ArrayList
?
Vector.ToArray(T[])
